The Gurghiu Mountains (Romanian: Munții Gurghiu [muntsʲi ɡurɡʲu], Hungarian: Görgény [ɡørɡeːɲ]) are a range in the Căliman-Harghita Mountains of the Eastern Carpathians, Romania, in the Transylvania region.
They are known for an abundance of wildlife, including deer, wild boar, wolves and bears.
In the north the Mureș River separates them from the Călimani Mountains.
To the south are the Harghita Mountains and the Târnava River Valley.
[3] The mountains were formed during a period of volcanic activity between 9.4 and 5.4 million years ago, starting in the north and moving southwards.
